Whoa, THAT Makes Me Old?

OK, so you can't stop time. But you can use these surprising tips to stay fit and sexy from now until..well, forever. Find out the surprising traits, behaviors and characteristics that can age you before your time.

1. Yo-yo sleeping habits
Clocking only a few hours weeknights and making up for it with 10-plus a night on weekends may disrupt your body’s renewal process on a cellular level.

2. Your fear of heights
Research suggests that phobic anxiety (the chronic OMG-I-cannot-deal kind, not mild occasional freak-outs) is associated with a chromosome change that’s linked to faster aging.

3. That daily Frapp
It’s a double whammy: All that sugar outweighs the antiaging perks of the caffeine. It breaks down skin’s collagen (the connective tissue that keeps you looking fresh). Plus, repeatedly using a straw can create fine lines around your mouth.
